ok what's up HT on the back of my B18A1 intake manifold there is two hoses. One goes to the coolant pipe that's connected to the water pump and the other is supposed to go to the throttle body and I was replacing it because it is broke. But I'm running a BWR throttle body and I don't see any plugs for the hose to slip on to. So would I have to plug the part that comes from the back of the intake manifold since it has no where to plug into? (First pic) I also don't know what plugs into the right hand side of the base of the intake manifold? (In the second pic)

. I found this pic but I don't have any plugs in my throttle body. What do I do just plug it?

Don't make this too hard... since you no longer have the inlet barb on the throttle body nor the FITV with the outlet barb, you simply need to connect the a hose from the IACV valve outlet barb in your first picture directly to the intake manifold inlet port in your second picture.

thanks man haha I'll post a picture later to make sure I have this right. Wasn't sure on what I'm doing so I wanted to make sure of things.

I ordered this hose in mistake for the barb that comes off the coolant pipe about a week ago. But I already had the hose just plugged up wrong. Well this works out great. But let me know if things look right? This other hose is unplugged in purpose for the picture.

That is pretty much the same routing I had for my b16a2 in my EM1 back when I was running a type-r intake manifold, when I switched to my skunk2 ultra street I lost that extra nipple on the intake and had to use the one near the thermostat housing. I kept having leaking issues on both ends of the IACV coolant lines, so I just pulled them and just run the IACV without coolant. lol

so do I have things looking right then?

From what I can see you should be fine, just make sure you have all of your other hoses connected and any unused nipples capped.

Yes, that is exactly as I instructed. Run it.

ok cool!! And it appears all the barbs are plugged in. I'll do a check over.
